MySQL Server Error Constants.
Covers up to MySQL 8.0.19. Notice that some constants were renamed in later versions of MySQL, because they became obsolete. (In case you wonder: the names here match the symbols MySQL uses in source code.) Obsolete names haven't been changed in this package to avoid breaking code, but you should no longer be using them in applications. New and/or changed names (symbols) are given in inline comments.
